No Internet Connection

I got into my office this morning and discovered that the server (windows 2003) could not connect to the internet and hence I cannot receive e-mails etc. It was working yesterday when I left. I tried pinging the router but it timed out.
I connected another computer directly to the router and this works and lets me ask this question. There are no error messages on the server and I'm not sure where to start looking.

All of the connection lights are on and the icon on the monitor shows a WAN connection.
I have decided to run a full virus scan before doing anything else.

Very Strange.
After re-boot I logged on to the server and I can now reach the internet but I still cannot reach the internet from any workstation.

Hi Bob:

I have an article for you to read.

I am thinking your preferred DNS servers are not correct.
